The cams of
camshaft driving
fuel pump can be adjusted to advance or delay
fuel injection to
engine cylinder. The cams driving
push rods for
inlet and exhaust valves can also be adjusted.
In doing all these adjustments, care must be taken to consider
positions of
piston relative to
process to be adjusted.
The flywheel at
end of
crankshaft is usually marked as a reference to show
piston at Top Dead Center. Each piston will have its marking on
flywheel. If
engine has 6 cylinders, then 6 markings for Top Dead Center will be marked.
From
markings on
flywheel a person can refer to it for adjustments on
fuel pump cams, and cylinder valve cams.
Some diesel engines do not have inlet and exhaust valves. Perhaps we will look at 2-stroke and 4-stroke diesel engine next...
Well folks, start your engines.
